Abstract:
A method for reclaiming an out-of-spec emulsion material includes recovering the out-of-spec emulsion material from a scrap manufacturing batch; distilling the out-of-spec emulsion material to raise a solids content of the out-of-spec emulsion material to about 45 wt % or more based on a total weight of the emulsion material; dissolving the distilled emulsion material in a solvent to form a first mixture; adding a base to the first mixture to neutralize acid groups present in the distilled emulsion material, forming a second mixture; emulsifying the second mixture by adding water to the second mixture; and forming particles having an average particle diameter (D50v) within a target range, wherein the out-of-spec emulsion material has an average particle diameter falling outside of the target range.
